Mac

brew cask install syncthing

If you run into any issues (for e.g., Syncthing doesn’t start), try starting the daemon through the command line to see what the problem is:

/Applications/Syncthing.app/Contents/Resources/syncthing/syncthing

Startup

syncthing --gui-address=0.0.0.0:8384 &

UI is available here as long as the above command is running.
